Succesful install, now black screen at boot

Posted 03 June 2013 - 10:14 AM

Hi guys! I have an old HP 625 that has amd. I had real issues when it comes to installing but after alot of trial and error I got install to work perfectly. I used these commands for other people:

-amd arch=i386 busratio=20 maxmem=2048 cpus=1 -v -f

Now when booting up with verbose I see alot of files loaded. Then screen just becomes black. Without any flags it reboots but a mix of above flags I get to a black screen.

I believe it could be my graphic card that is not supported!?!?! Can I fix this in some way without being inside macosx? I guess making a boot usb where I can install drivers would do it?

It is a Radeon HD 4200 and reading about it just now tells me it should work in macosx. I might have NOT ticked it in in the install. Can I post-fix this or just need to reinstall osx with ati radeon ticked in?

I am runnning a HP 625 with amd athlon II p320 processor. I have installed Iatkos S3 V2 using qoopz 10.3.0 kernel and also qoopz 10.2.0 kernel but for some reason I can't seem to get trackpad or USB mouse working. I also have to use the above flags to get it to boot. Anybody with a solution?
